I think you should be stop a few day then learn and review your mistake in trading. After find it, learn and review it then you can continue trading with new strategy and new risk management. My opinion your mistake is not use stop loss, before trading should be decide the amount of stop loss and take profit, for example stop loss 15% and take profit 25% and also use daily chart so more accurate to decide when buying and selling.
Or even he didnt tend to put stoploss after all and i do presume that he did make a panic sell when he saw that prices are already dropping. Lossing 40% is serious loss which we would really panic if we saw our capital is slowly depleting and times that we wont know already on what we gonna do. As being suggested have a break and analyse your mistakes and see where you did make a wrong decision to commit such loss. Any mistakes should really be learned off later on and we should expect losses to since theres no perfect trader on this world. I had loss almost 50% income and I didn't stop because I know that the problem is within me an not with trading. I was just enjoying earning bitcoin but I thought of trying out new things so I entered altcoin and trading. Being a newbie trader I also made a mistake of panic selling when I saw that the price is dropping and that was when I loss a huge profit. But that didn't stop me from trading, what I did is I accepted my failure and treat it as a learning experience.
You could also do the same thing. After all, the market price of bitcoin is on pump again.
